Parameter Controllers

Some parameters like float can be controlled with different controllers. For instance:

• knob
• slider

Other parameter types (data types) such as color can be controlled with:

• 4 sliders (RGBA)
• color picker

A color controller.

Most controllers can be closed by left-double-clicking them.
